The E-sCAiO, N-CAiO modules automatically identify the anesthetic
agent present in the sampled gas and measure the concentration
of the identified agent.
Identification threshold
Identification time
The E-sCAiO module automatically identifies mixtures of two
anesthetic agents present in the sampled gas and measures the
concentrations of the two identified agents.
Identification threshold for
the second agent at 1 MAC
